This invention relates to sash windows and more particularly refers "to improvements in windows ofthe type where the window sashes may be made to swing inwardly about a lateral hinged support, in order to facilitate cleaning and washing operations.

The primary object of this invention is to provide a window structure where window sashes of ordinary design are mounted so as to be slidable up and down while at the same time being adapted to be swung inwardly without materially disturbing the arrangement of the window frame. 7

Another object is to provide a sash window of the character specified in which the use of double sash frames is avoided; sash frames of ordinary design and dimensions being carried by hinged supports which are in themselves vertically slidable between the guiding strips of the window frame.

A. further object is to provide a sash window combining into one the advantages of sliding and swinging sashes, the construction of which is substantially identical with slight additional cost.

that of windows and window frames in current use, except for some modifications of a simple nature which can be introduced at A still further object is to provide in a window structure of-the character specified, an improved arrangement of guiding strips insuring at 1 all times the rigidity and strength of the runways provided for the sides of the window sashes.

Other objects and advantages of the present invention" will more fully appearas the description proceeds and will be set forth and claimed in the appended claims.

An embodiment of my invention is illustrated in the accompanying drawings, in which: r V

Fig. 11 is a detail vertical section through line 1111 of Fig. 10.

Referring to said drawings, the window frame, of ordinary construction, comprises a top 10, a sill 11 and two sides 12, 13. In said frame are mounted so as to be vertically slidable an upper sash 14 and a lower sash 15 which are off-set one from the other as shown in Fig. 3 in order to permit their independent up and down movements.

21 and by intermediate guiding strips 22, 23.

In a similar manner the front sash slides in two runways24, 25 formed by intermediate guiding strips 22, 23 and by front guiding strips 26, 27

The sash frames are counterbalanced by weights 2829, 3031, attached to cords such as 3233, running over pulleys 3435 at opposite sides of the window frame.

The guiding strips 20, 22, 26 at one side of the window frame are recessed to form edges of hinge members upon which are pivmove unhampered up or down.

tudinal grooves 3 "22 and 26. r

V The hinge. members carried by the lower r p "is preferably provided at its lower endjwith va downwardly projecting pin 54; andiat its upper end it may beprovided'with a handle orcatch 58j'pivotally mounted at 59 and room for the swinging movement of the I is preferably near the lower end of the '--winotally mounted other hinge members attached to the corresponding side of the sash. Thus the left side 38 of the upper sash is mounted on hinge members '39, 4.0 of two hinges, the other hinge members 41 of which.

have their front and rear. edges-projecting within grooves 37 formed by guiding strips 20, 22. The two hinges are vertically spaced .a sufiicient distance to provide a relatively long guiding support, for the sash.

The front part of hinges 39, 40 is preferably fiat, the hinge members being connected a pivot 42 in close'proximity of the surface of guide strip 22, said pivotal .connection projecting-no more than ledge 17 from the surface of the sash frame so-thatclearance 16 will be suflicient topermit the sash. to

The lower sash is similarly mounted on hinge: members 43, 44 'pivotally connected at 45 to hinge memberstfi having their front and rear edgesslidably inserted with in longi- 7 formed by guiding. strips sash are'preferably bent forwardly at right angle asshown at 47 so that the hinge connections 45 remain spaced a certaindistance' from the front surface of the sash frame.

This arrangement permits of swinging the lower sash frame arelatively wide angleas shown 1n Flg. 18, so as to leave ample upper sash frame. 1

In Figs. 10, 11,1 illustrate in detail the'preferred construction of hinge. In the same" it is seen thatthe hingemember 39 is pivotally connected at 42 to the'plate member which comprises a relatively wide plate l1 and another narrower plate 41 connected to plate ll by means of rivets 48 01- in any other suitable manner. Y z

Platetl iswider than the vertical runway 18, its front and rear edges A9,;50 extending within recesses 37 which form a supplemental relatively shallow runway wider than the 'main'runway 18. i j

' By virtue of this arrangement, the plate member l-l tl can slideup and down the runway but cannot come oif, so that it forms asliding support for the sash frame attached thereto.

r "In order to furtheriinsure smooth opera- ;tion of the sash frames, I. prefer to form the same with a recess 51 adapted to receive plate 4141 when the sash frame occupies its normal position. In this manner the sash frame registers with the runway along its entire length, and a smoother operation results. p

. At" the side of the window frame opposite '52 the length of which is at least equivalent to the height of each sash frame. v

A removable strip section 53 can be placed in position to complete the guiding strip filling said gap, said strip section being preferably provided with a pin 54: downwardly projectingfrom ,its lower end, insertable through an opening 55 provided of the lower tract of strip 27. Y

Saidremovable section is also preferably at V the top provided with outwardly projecting buttons '55 adapted to be inserted and'reta-inedwithin frictional housings such as 56located within;

the'window. frame,so that the movable strip sectionmay befeasily placed in positionor removed therefrom.

. In a similar manner a portion of guiding strip 23 is cut off in correspondence of-gap 52 of strip 27 so as to form a gap 52. which can be filled by another detachable strip' section 57 as shown in Fig. 5. Y

Like in the previous case, strip section 57 dow frame'but spaced therefrom. As a result, the stationary lower. strip sections 27, '23. provide a' rigid abutment for the lower sash framewhen the window is closed, making it impossible for the sash to come. loose, of lts own accord due'to wlnd pressure or other causes. i

The removable section 57 of "guiding strip 23 is normally retained in'position by the ledge portion 17 of the upper sash frame,

as clearly shown inFig..2'.

is necessary to clean the glass panes the strip section 53 is first removed, then the" lower sash frame is raised to register with gap 52 left by the removal o fsaid strip section. j The necessity of a person having to set onthe ledge and lean outside. i

i The upper sash is then-lowered to a position where its ledge 17 clearsstrip section 57, and catch 58 is taken hold-of at 58" so as to remove the strip section as shown in Fig.

The sashes, are operated in the usual'manher for thepurpose ofventilation. Then it 'replaced, after which the lower sash is swung back into position and strip section 53 is replaced so as to fill gap 52.

It will be observed that my invention entails but few changes in the construction of window frames now currently in use; the

, only changes being practically the recessing of the guide members at one side of the frame to provide the supplemental runways for the plate members of the hinges, and the cutting off of a portion of the guiding strips at the opposite side in order to provide a clearance through which the sash frames may be caused to pass during their swinging movement.

Owing to the simplicity of the arrangement it is therefore possible to employ the same in connection with window frames of standard design and it is also possible to make the necessary changes in existing windows.

The cords from which the counterweighis are suspended are'preferably attached to the sash frames, by means of hooks such as 61 (see Fig. 9), this arrangement permitting the free swinging of the sash frames at their attaching side and permitting the cords being quickly detached from and re-attached .to the sash frames at the opposite side.

The constructional details of my invention may vary to a certain extent from those shown without departing from the inventive idea; the drawings will therefore be understood as being intended for illustrative purposes only and not in a limiting sense.

Accordingly, I reserve the right to carry my invention into practice in all those ways and manners which may enter, fairly, into the scope of the appended claims.

I claim:
